Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641882, here are decompositions:

101 + 8641781 = 8641882
149 + 8641733 = 8641882
173 + 8641709 = 8641882
239 + 8641643 = 8641882
251 + 8641631 = 8641882
269 + 8641613 = 8641882
311 + 8641571 = 8641882
449 + 8641433 = 8641882

Showing the first eight; more decompositions exist.
